Müllerian mimicry in Dendrobates frogs near Tarapoto,
Peru
(a - c) The three frogs are all putative members of a single species,
Dendrobates

species in a different geographical region. The species with which each
morph is sympatric is shown directly below that morph. From left to right,
the species in (d - f ) are: Dendrobates variabilis (Tarapoto),
Dendrobates
fantasticus (Huallaga Canyon) and Dendrobates ventrimaculatus (Yurimaguas).
